摘要:

图神经网络(GNNs)通过消息传递机制在节点分类任务中展现出强大潜力。然而,其性能往往依赖于高质量的节点标签,而在现实场景中,由于不可靠的来源或对抗性攻击,高质量标签难以获得。因此,标签噪声在现实世界的图数据中普遍存在,通过在训练过程中传播错误信息对GNNs产生负面影响。为解决这一问题,标签噪声下图神经网络(GLN)的研究近年来逐渐受到关注。然而,由于数据集选择、数据划分和预处理技术的差异,该领域目前缺乏一个全面的基准,这阻碍了对GLN的深入理解和进一步发展。为填补这一空白,我们在本文中提出了NoisyGL,这是首个针对标签噪声下图神经网络的综合基准。NoisyGL通过统一的实验设置和接口,能够在各种数据集的噪声标签图数据上对GLN方法进行公平比较和详细分析。我们的基准揭示了以往研究中被忽略的若干重要见解,我们相信这些发现将对未来的研究大有裨益。我们希望我们的开源基准库能够促进该领域的进一步发展。该基准的代码可在 https://github.com/eaglelab-zju/NoisyGL 获取。

英文摘要:

Graph Neural Networks (GNNs) exhibit strong potential in node classification task through a message-passing mechanism. However, their performance often hinges on high-quality node labels, which are challenging to obtain in real-world scenarios due to unreliable sources or adversarial attacks. Consequently, label noise is common in real-world graph data, negatively impacting GNNs by propagating incorrect information during training. To address this issue, the study of Graph Neural Networks under Label Noise (GLN) has recently gained traction. However, due to variations in dataset selection, data splitting, and preprocessing techniques, the community currently lacks a comprehensive benchmark, which impedes deeper understanding and further development of GLN. To fill this gap, we introduce NoisyGL in this paper, the first comprehensive benchmark for graph neural networks under label noise. NoisyGL enables fair comparisons and detailed analyses of GLN methods on noisy labeled graph data across various datasets, with unified experimental settings and interface. Our benchmark has uncovered several important insights that were missed in previous research, and we believe these findings will be highly beneficial for future studies. We hope our open-source benchmark library will foster further advancements in this field. The code of the benchmark can be found in https://github.com/eaglelab-zju/NoisyGL.
